Hi @devilaunz4 and welcome to the Cayenne community! The Node MCU is an ESP8266 based board, and while we have lots of users in the community who are successfully using ESP boards with Cayenne, we don’t have it in the product UI yet – so you’re not going crazy, it will appear there as a menu option in the future. 
In the meantime, start with this thread on connecting ESP8266 to Cayenne, especially the example code in this post, and feel free to use all of us in the community as a resource if you get stuck or have questions.
